With over 3,800 GitHub stars and continuous development since 2002 spanning 24 years of active maintenance through version 16.4.0 released in May 2026, Piwigo has proven itself as one of the most battle-tested self-hosted photo gallery platforms available, trusted by professional photographers managing 150,000+ high-resolution images alongside small teams sharing event photos. The PHP backend with MySQL or MariaDB storage serves a responsive web interface that organizes photos into hierarchical albums with nested sub-albums, tag-based categorization, and smart albums generated dynamically from search criteria. Batch management tools handle bulk uploads, metadata editing, tag assignment, and album moves across thousands of images simultaneously. User permission controls define access at the album level with configurable public, private, and group-restricted visibility, while guest access allows public galleries without authentication. Image processing via ImageMagick or PHP GD generates multiple thumbnail sizes, watermarks, and responsive derivatives automatically. The plugin ecosystem with over 200 community-built extensions adds functionality from EXIF metadata display and GPS mapping to social sharing, download controls, and Lightroom synchronization for desktop workflow integration. The REST Web API with personal API key authentication enables programmatic album creation, photo uploads, and metadata queries from external applications. Mobile apps for iOS and Android provide on-the-go upload and browsing capability. Docker deployment via the official container or traditional LAMP installation on any hosting provider. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0 licensed.

Stocks, ETFs, crypto, bonds, precious metals, and cash across every account and currency, in one privacy-first dashboard: Ghostfolio is open-source wealth management software. The deliberate design decision is no brokerage linking: positions enter by manual entry, CSV import, or the REST API, so your holdings never pass through a data aggregator. Performance is measured as return on average investment across Today, WTD, MTD, YTD, 1Y, 5Y, and Max timeframes, with benchmark comparison against indices like the S&P 500, dividend tracking, and allocation breakdowns by asset class, region, and sector. A static X-ray analysis flags concentration and other portfolio risks, and a FIRE calculator projects progress toward financial independence. Multi-currency support converts holdings using historical exchange rates, market data comes from Yahoo Finance and CoinGecko among other pluggable providers, and everything exports back out as CSV or JSON. Built with Angular and NestJS on PostgreSQL and Redis, shipped as Docker images for amd64 and ARM, with a mobile-first PWA interface, dark mode, and a distraction-free Zen mode. AGPL-licensed.

Some messages should only arrive if you cannot send them yourself, and Aeterna is a self-hosted dead man's switch that makes sure they do. You write the messages, attach the files that matter, name the people who should receive them, and check in on a rhythm you choose. Keep checking in and nothing happens. Stop, and Aeterna delivers what you left behind. Each switch pairs your words with documents, photos, or instructions for specific recipients, and switches can address multiple recipients so one message can reach a partner, a sibling, and a lawyer at the same time. File attachments are stored encrypted and are automatically deleted from the server right after delivery, so sensitive material does not linger once it has done its job. Check-ins take seconds through the web interface or a quick link in your email, which keeps the heartbeat habit painless. When a switch fires it can also call webhooks, triggering home automation or custom scripts alongside the emails. Your SMTP settings live in the settings screen with live testing, and reverse proxy templates for Nginx, Traefik, and Caddy help you put the service behind your own domain with proper certificates. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Only the person holding the link can open what you share with SkySend, a self-hosted file and note sharing service that encrypts everything in the browser before it leaves your device. Sending a contract? Drop in the file, several files, or a whole folder, and share the link. Need documents from a client? Send an upload link instead, and whatever comes back is encrypted for you alone. Handing over a password or an SSH key? Write it into a note that burns after reading. Notes can mix text, Markdown, generated passwords, and highlighted code in a single page. Every share can expire by time, stop after a set number of downloads or views, and carry an optional password as a second lock. The command-line client uploads, downloads, and reads notes with the same encryption, and its full-screen mode shows each link as a QR code. No accounts are needed: My Links keeps your shares in the browser, and optional OIDC sign-in limits who may create them. Encrypted uploads sit on local disk or any S3-compatible bucket, and the interface offers 13 languages and three themes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Real-time alerts from your own infrastructure to your phone, with no Firebase, Pushover, or third-party push service in the path: Gotify is a simple, self-hosted notification server written in Go. The model is deliberately minimal: senders push messages with a single HTTP POST to the REST API, receivers subscribe over a WebSocket stream, and a clean React web UI manages the pieces. Senders are namespaced as "applications," each with its own token, so your backup script, Uptime Kuma, CI pipeline, and cron jobs each get an identity, an icon, and independently revocable credentials - centralized alerting from many services with per-source management. Messages carry a title, body, and priority level that maps to notification importance on the client. The official Android app (on both F-Droid and Google Play, notable for working entirely without Google Play Services) shows push notifications for new messages; the web UI itself supports Web Push in the browser; and gotify/cli pushes messages from shell scripts with one command. A server-side plugin system adds custom behavior, and the whole thing runs as a single small binary with SQLite by default - near-zero resource footprint. Because dozens of tools (and Apprise) speak Gotify natively, it slots in as the notification hub for an entire homelab or ops stack.

Up to 280 search services - Google, Bing, DuckDuckGo, Brave, Qwant, Startpage - aggregated without tracking or profiling: SearXNG is a privacy-respecting metasearch engine (AGPL-3.0, successor to Searx). Your instance queries the upstream engines on your behalf: your IP address, cookies, and search history never reach them, tracker parameters are stripped from result URLs, and an optional image proxy fetches thumbnails server-side so result pages leak nothing. It can even route outbound queries through Tor for full anonymity. Search is organized into categories - general, images, videos, news, maps, music, IT, science, files - with bang shortcuts for targeting specific engines, and every source can be enabled, disabled, or weighted per category in settings.yml. A plugin system adds calculators, hash tools, tracker removal, and unit conversions inline, and preferences (themes, safe search, languages, engine selection) persist in cookies rather than server-side accounts. The real argument for running your own instance rather than trusting a public one is control: you decide the logging policy (none), the engine mix, rate limiting, and who gets access - making it the default search backend for browsers, families, and teams that want Google-quality results without the profile.

Give every website its own email address and your real inbox stays yours alone with AnonAddy, a private email forwarding service where [email protected] and [email protected] land in one inbox and hide the real address behind them. Create aliases on the fly from your username, generate random character or random word aliases that cannot be linked back to you, and label each one so you know exactly which site handed it out. When an alias starts attracting spam, deactivate it to silently discard mail or delete it so senders get a bounce, and the rest of your addresses keep working untouched. Reply to forwarded mail or start new conversations from the alias itself, so recipients never learn your real address. Attach your own domain or subdomain with MX records and make any address on it, add GPG or OpenPGP encryption so forwarded mail arrives encrypted, and strip tracking pixels before messages reach your client. Rules act on matching mail by blocking senders, changing recipients, rewriting subjects, or firing webhooks, and a REST API plus browser extension and Bitwarden integration create aliases right where you sign up. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Stop pasting your files into ad-riddled online converters and handing strangers copies of your documents: HRConvert2 runs the whole conversion workshop on your own server instead. Drop a file onto the browser page and pick an output format from a catalogue of 488, covering documents, spreadsheets, presentations, ebooks, comics, images, audio, video, subtitles, and archives. Built-in OCR reads scanned PDFs and images and hands back editable text documents you can search and reuse. It converts 3D models and CAD drawings, renders OpenSCAD projects with their multi-file assemblies resolved, and can even build bootable ISO disk images for x86 and ARM machines from ordinary uploads. Live streams are captured and re-encoded straight from .m3u8 playlists, and every uploaded file can be virus-scanned with ClamAV before or after conversion. Finished files go back out through temporary share links that expire on their own, so sending a converted video to a client takes one click. Each visitor works in an isolated scratch space, files delete themselves when they age out, and nobody needs an account, ever. When traffic spikes, the server watches its own CPU and memory, throttles conversions, and spreads storage across disks so it stays upright. Three interfaces, seven color schemes, and 26 languages let each user shape the page to taste, and the whole thing runs happily on a Raspberry Pi with no database at all. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Live web search plus an LLM of your choice: Farfalle is an open-source, self-hosted answer engine in the Perplexity mold. Queries route through one of several search providers - self-hosted SearXNG for a fully independent stack, or Tavily, Serper, and Bing APIs - and the model composes a cited answer from the retrieved results. Model flexibility is the core design: run llama3, mistral, gemma, or phi3 locally through Ollama for zero per-query cost and full privacy, use cloud models like GPT-4o or Groq-hosted Llama 3 for speed, or route to any provider via LiteLLM. An Expert Search mode uses an agent that plans a multi-step search strategy and executes it for harder questions, and chat history keeps prior research sessions available. The stack is a Next.js and shadcn/ui frontend over a FastAPI backend with Redis rate limiting, shipped as a pre-built Docker image. A browser search-engine entry pointing at your instance makes it the default search from the address bar. Paired with SearXNG and Ollama, the whole pipeline runs with no external API at all.

Large link collections stay fast and organized in Faved, a private, self-hosted bookmark manager built for exactly that job. Its core is a nested tagging system that outgrows flat folders: place Go and Python under Programming Languages, color-code tags, add descriptions, pin frequent ones to the top of the sidebar, and optionally roll up child-tag items into parent views. Saving is frictionless - a lightweight bookmarklet works in any desktop or mobile browser without extensions, and Apple devices can send links through the native Share menu. Faved fetches titles, descriptions, and preview images automatically, keeps that metadata fresh over time, and flags duplicates as you save. Instant as-you-type search, flexible sorting, and bulk actions (retag, delete, refetch) keep collections of any size manageable, while customizable layouts - card, list, or table - plus a system-synced dark mode adapt the interface to your workflow. Migration is first-class: import from Chrome, Safari, Firefox, or Edge with folder structure preserved, or move from Pocket and Raindrop.io keeping tags and collections. The stack is deliberately light - PHP 8 with SQLite behind a React/Tailwind frontend - deploying via Docker with no external dependencies. All data stays local: no ads, no tracking, and no risk of your library vanishing with a discontinued service.

Real LibreOffice document engineering in the browser: Collabora Online is built by the company employing much of the former SUSE LibreOffice team - not a reimplementation. This deployment runs CODE (Collabora Online Development Edition), the collabora/code server that renders and edits documents entirely server-side while browsers get high-fidelity WYSIWYG output, so layout and formatting survive round-trips that break lesser converters. Four editors ship in one container: Writer for text documents (comments, track changes with comparison and restoration, form handling), Calc for spreadsheets (advanced formulas, macros, pivot tables, per-user sheet views, server-enforced cell protection), Impress for presentations, and Draw for Visio-class diagrams. Format compatibility spans DOCX, XLSX, PPTX, the ODF family, PDF, and dozens more - including Visio and Publisher import. Real-time collaborative editing supports multiple simultaneous editors with visible cursors and commenting. The architectural point: documents are processed on your server and never leave it, which is why Collabora is the engine behind Nextcloud Office and integrates with ownCloud, Seafile, and any WOPI-speaking host - or embeds in your own application via the SDK. An admin console monitors sessions and memory. For organizations that need Google Docs-style collaboration with actual data sovereignty, this is the reference open-source answer.

Most file sharing leaves copies lying around forever; Tessera shares things with a built-in goodbye. Drop in a file, a whole folder, a code snippet, or a link and you get back a short code and a URL that anyone can open until it expires or hits the download count you set, at which point it is deleted. Expiry is checked on every request and each retrieval is counted atomically, so a one-time share cannot be raced by two people at once. Passwords can be required before anything is shown, code arrives syntax-highlighted, and images, SVGs, and diagrams preview in the page, with link cards when you paste the URL into chat. Uploads resume after interruptions and stream through the server without ballooning memory at any size. Behind the scenes you choose where bytes live: local disk, S3-compatible storage, Azure Blob, Google Cloud Storage, or WebDAV, several at once, added or retired from the admin panel without a restart. Accounts are optional for a home server, sign-in through OpenID Connect suits a team, and roles with per-account quotas decide who may upload, view everyone's shares, or change settings. Optional malware scanning, anonymous-upload caps, and rate-limited code lookups keep a public instance honest. A CLI and API tokens drive the same endpoints as the web app, so scripts can share and clean up exactly like people. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Perplexity's answer-engine experience, self-hostable and open-source: Morphic searches the web and writes cited answers. Instead of returning a list of links, it searches the web, reads the sources, and generates a complete answer with inline numbered citations. The generative UI streams rich components, source cards with thumbnails, image grids, syntax-highlighted code, and LaTeX math, rather than plain markdown. Quick mode answers fast; Adaptive mode runs deeper multi-step research. Search backends are pluggable: the Docker Compose bundle ships with a private SearXNG instance so no search API key is required, and Tavily, Brave, and Exa are supported alternatives. LLM providers include OpenAI, Anthropic, Google, Ollama, and any OpenAI-compatible endpoint, with per-mode model mapping - fast, cheap models for quick searches, stronger models for adaptive research, tuning the cost-quality trade-off per query type. An inspector panel exposes tool execution during multi-step research, and AI-suggested follow-up questions keep an investigation moving. Chat history persists in PostgreSQL, results are shareable by URL, file uploads feed context into queries, and optional Supabase authentication adds multi-user or guest access. Because the default search path is your private SearXNG instance, research topics never hit a commercial search API - and with local Ollama models the marginal cost of a query approaches zero. Built with Next.js, TypeScript, and the Vercel AI SDK under Apache 2.0.

Nod is a personal AI assistant with its own computer, so you can hand it an errand like chasing an unpaid invoice or cancelling a trial and watch it finish the job on real websites. One ongoing conversation follows you from the browser to Telegram and WhatsApp, and long jobs become saved tasks with live status lines on a Scheduled page. Connect Gmail, Calendar, Slack, Notion, Linear, or an n8n instance, and it reads threads, drafts the replies you owe, and prepares a one-page brief before each call. Every action that could change something is checked against your rules, and anything uncovered waits for your yes. Passwords, codes, and cards sit in a Vault that the server types into websites, so the model never sees them. Memory notes are visible, editable, and tied to the message they came from. Schedules run recurring checks like a weekly recap or a price watch that speaks up only on change. Usage lists every action with costs and a monthly spending limit. Pick OpenAI, Anthropic, Gemini, OpenRouter, Bedrock, or a local Ollama server as the model. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Grammar, punctuation, and style errors a dictionary lookup can't see: LanguageTool is open-source proofreading powered by a Java rule engine covering English, German, Spanish, French, Portuguese, Dutch, and 25+ other languages. Self-hosting the HTTP server is how you get Grammarly-class checking without sending every sentence you write to a third party - a real concern when the text being proofread is confidential email, legal drafts, or unreleased documentation. Your instance exposes the standard /v2/check API, so the official ecosystem plugs straight in: browser extensions for Chrome and Firefox accept a custom server URL, and integrations exist for VS Code, LibreOffice, Obsidian, Vim, Emacs, and many editors. Notably, self-hosting restores free browser-extension checking that the hosted service moved behind a premium subscription - your server, no character limits, no paywall. Detection quality is tunable: optional n-gram datasets (multi-gigabyte language models for en, de, es, fr, nl) teach the engine word-order and confusion-pair errors like there/their and brakes/breaks, and a fastText model improves automatic language identification. Everything runs offline once models are downloaded. The core is LGPL, the API is documented with Swagger, and rules are community- maintained and constantly expanding.

With over 9,000 GitHub stars earned since Google killed its browser-based Timeline, Dawarich fills the gap with a fully self-hosted location history platform that keeps your movement data under your control. Built on Ruby on Rails 8.0 with PostgreSQL and the PostGIS spatial extension for geometry-based queries, Dawarich imports your entire Google Takeout location archive in minutes and begins rendering interactive maps immediately. The visualization engine supports five map layers — heatmaps, points, lines, Fog of War exploration tracking, and a 3D globe view — each powered by Leaflet and spatial SQL rather than browser-side computation. Native iOS and Android apps handle background GPS tracking with offline support, automatically uploading location points when connectivity returns, while third-party integrations support OwnTracks, GPSLogger, Overland, Home Assistant, Traccar, and PhoneTrack. The trip system lets you create route visualizations between any two dates, attach notes, replay travel paths with a timeline scrubber, and share trips publicly with phrase-protected links and per-section visibility controls. Immich and PhotoPrism integrations automatically overlay geotagged photos on your maps and trips, while AirTrail integration renders flight history as arcs. Statistics dashboards break down countries visited, cities explored, total distance traveled, and active days by year and month, with visit detection suggesting places you have frequented. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

FlyBudget gives every dollar a job and keeps your financial data on a server you control, with no subscription, no account, and no tracking. Plan each month by category with carry-over, and watch bars turn amber near the plan and red when you overspend. Write a rule in plain words, preview the past transactions it matches, and let it rename, categorize, or split everything that arrives next. Track checking, credit cards, loans, investments, and property in their own currencies, then reconcile when the numbers need proof. Import CSV files from any bank with duplicate detection, or connect SimpleFIN or Plaid for automatic sync. Bills, subscriptions, and paychecks appear as a list or calendar, and FlyBudget can find them in your history. Dashboards of net worth, spending, trends, and cash flow can be rearranged, and a custom report builder covers the rest. Savings goals, payees with logos, and one-step backups sit alongside light and dark themes. Every page has a phone layout, and transactions entered offline sync when the connection returns. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

On your own server, TypeType runs a private video platform for YouTube, NicoNico, and BiliBili, keeping subscriptions, history, and playlists out of someone else's recommendation engine. Pick a service and search it. Browse channels, Shorts, podcasts, and a home feed. Speed and quality control. Cinema mode. Native picture-in-picture. Subtitles, alternate audio tracks, and frame-by-frame stepping. SponsorBlock segments get skipped, or just marked, by category. Subscriptions, playlists, watch later, favorites, and resume positions fill the library. Import a Google Takeout export or a PipePipe backup and a new instance never starts empty. Download video or audio to local or S3-compatible storage and collect it in the browser when it is ready. Sign in locally or through OIDC. An admin console runs the instance. Block a channel and it disappears from feeds, search, and related videos. Hide Shorts. Hide personalized recommendations. Hide the suggestions column. A native Android client for phones and tablets syncs with the same instance. An optional experimental recommender can build a personalized home feed, and each user chooses whether to turn it on. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
